      3 # Notes:
      4 #	* no obj dir support
      5 #	* kernel headers are supposed to exist, i.e. they're not
      6 #	  expected to be built.
      7 #
      8 # System configuration variables:
      9 #
     10 # SYS_INCLUDE	"symlinks": symlinks to include directories are created.
     11 #		This may not work 100% properly for all headers.
     12 #
     13 #		"copies": directories are made, if necessary, and headers
     14 #		are installed into them.
     15 #
     16 # Variables:
     17 #
     18 # INCSDIR	Directory to install includes into (and/or make, and/or
     19 #		symlink, depending on what's going on).
     20 #
     21 # KDIR		Kernel directory to symlink to, if SYS_INCLUDE is symlinks.
     22 #		If unspecified, no action will be taken when making include
     23 #		for the directory if SYS_INCLUDE is symlinks.
     24 #
     25 # INCS		Headers to install, if SYS_INCLUDE is copies.
     26 #
     27 # SUBDIR	Subdirectories to enter
     28 #
     29 # SYMLINKS	Symlinks to make (unconditionally), a la bsd.links.mk.
     30 #		Note that the original bits will be 'rm -rf'd rather than
     31 #		just 'rm -f'd, to make the right thing happen with include
     32 #		directories.
